get-mailbox-settings
Read-only

Retrieve a user's mailbox settings including automatic replies, time zone, date/time formats, language, and more. View all settings or select specific ones.

Instructions

Get the user's mailboxSettings. You can view all mailbox settings, or get specific settings. Users can set the following settings for their mailboxes through an Outlook client: Users can set their preferred date and time formats using Outlook on the web. Users can choose one of the supported short date or short time formats. This GET operation returns the format the user has chosen. Users can set the time zone they prefer on any Outlook client, by choosing from the supported time zones that their administrator has set up for their mailbox server. The administrator can set up time zones in the Windows time zone format or Internet Assigned Numbers Authority (IANA) time zone (also known as Olson time zone) format. The Windows format is the default. This GET operation returns the user's preferred time zone in the format that the administrator has set up. If you want that time zone to be in a specific format (Windows or IANA), you can first update the preferred time zone in that format as a mailbox setting. Subsequently you will be able to get the time zone in that format. Alternatively, you can manage the format conversion separately in your app.

đź’ˇ TIP: Gets the current user's mailbox settings including automaticRepliesSetting (out-of-office status, message, scheduledStartDateTime/EndDateTime, externalAudience), language, timeZone, dateFormat, timeFormat, delegateMeetingMessageDeliveryOptions, and userPurpose.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
expandNoNavigation properties to inline, e.g. attachments on a message or event. Only navigation properties can be expanded: expanding a non-navigation property such as a message body fails with "Parsing OData Select and Expand failed", and an unsupported value may be ignored rather than reported. Request ordinary fields with $select instead.
selectNoComma-separated fields to return, e.g. id,subject,from,receivedDateTime
fetchAllPagesNoFollow @odata.nextLink and merge up to 100 pages into one response. Can return enormous payloads—only when the user explicitly needs a full export. Prefer a small $top first, then paginate or narrow with $filter/$search.
includeHeadersNoInclude response headers (including ETag) in the response metadata
excludeResponseNoExclude the full response body and only return success or failure indication
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already provide readOnlyHint=true and destructiveHint=false. The description adds behavior details like date/time format handling and time zone format support (Windows vs IANA), which goes beyond annotations. No contradictions.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Description is somewhat verbose, especially the paragraph about date/time and time zone behavior. The TIP adds value but the structure could be leaner. Not overly concise.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no output schema, the description lists some return settings but lacks details on response structure (e.g., JSON object shape). It adequately explains behavior but could be more complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with descriptions for all 5 parameters. The description does not add parameter-specific info beyond what the schema provides, so baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool gets user mailbox settings and lists specific settings (automaticRepliesSetting, language, timeZone, etc.), distinguishing it from sibling tools like update-mailbox-settings.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Implied usage is for reading settings, but no explicit guidance on when to use vs. update-mailbox-settings or other sibling tools. The 'TIP' indicates it gets current user settings, but lacks direct when-to-use/when-not-to-use advice.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
